  2. Clarke Studies - Wikipedia

    en.wikipedia.org/wiki/Clarke_Studies

    The second volume, published in 1912 as Clarke's Technical Studies for Cornet, includes 190 exercises divided into ten studies with notes from the author suggesting how to practice them. Each of the ten studies concludes with an exercise serving as an étude , except for the ninth study, which lacks an exercise labeled as such, and the tenth ...

  3. Primes in arithmetic progression - Wikipedia

    en.wikipedia.org/wiki/Primes_in_arithmetic...

    The following table shows the largest known AP-k with the year of discovery and the number of decimal digits in the ending prime. Note that the largest known AP- k may be the end of an AP-( k +1). Some record setters choose to first compute a large set of primes of form c · p #+1 with fixed p , and then search for AP's among the values of c ...

  4. Twin prime - Wikipedia

    en.wikipedia.org/wiki/Twin_prime

    For a twin prime pair of the form (6n − 1, 6n + 1) for some natural number n > 1, n must end in the digit 0, 2, 3, 5, 7, or 8 (OEIS: A002822). If n were to end in 1 or 6, 6n would end in 6, and 6n −1 would be a multiple of 5. This is not prime unless n = 1. Likewise, if n were to end in 4 or 9, 6n would end in 4, and 6n +1 would be a ...

  5. Sexy prime - Wikipedia

    en.wikipedia.org/wiki/Sexy_prime

    If p + 2 or p + 4 (where p is the lower prime) is also prime, then the sexy prime is part of a prime triplet. In August 2014, the Polymath group, seeking the proof of the twin prime conjecture , showed that if the generalized Elliott–Halberstam conjecture is proven, one can show the existence of infinitely many pairs of consecutive primes ...

  6. Ages of Three Children puzzle - Wikipedia

    This gives the following triplets of possible solutions: ... 2: 2: 9: 13: 2: 3: 6: 11 3: 3: 4: 10 Using the same argument as before it becomes clear that the number ...

  7. Tuplet - Wikipedia

    en.wikipedia.org/wiki/Tuplet

    The most common tuplet [9] is the triplet (German Triole, French triolet, Italian terzina or tripletta, Spanish tresillo).Whereas normally two quarter notes (crotchets) are the same duration as a half note (minim), three triplet quarter notes have that same duration, so the duration of a triplet quarter note is 2 ⁄ 3 the duration of a standard quarter note.

  8. Prime k-tuple - Wikipedia

    en.wikipedia.org/wiki/Prime_k-tuple

    In number theory, a prime k-tuple is a finite collection of values representing a repeatable pattern of differences between prime numbers.For a k-tuple (a, b, …), the positions where the k-tuple matches a pattern in the prime numbers are given by the set of integers n such that all of the values (n + a, n + b, …) are prime.

  9. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    Any real number can be written in the form m × 10 ^ n in many ways: for example, 350 can be written as 3.5 × 10 2 or 35 × 10 1 or 350 × 10 0. In normalized scientific notation (called "standard form" in the United Kingdom), the exponent n is chosen so that the absolute value of m remains at least one but less than ten ( 1 ≤ | m | < 10 ).
