  2. Greater-than sign - Wikipedia

    en.wikipedia.org/wiki/Greater-than_sign

    In mathematical writing, the greater-than sign is typically placed between two values being compared and signifies that the first number is greater than the second number. Examples of typical usage include 1.5 > 1 and 1 > −2. The less-than sign and greater-than sign always "point" to the smaller number.

  3. Power of two - Wikipedia

    en.wikipedia.org/wiki/Power_of_two

    The only known powers of 2 with all digits even are 2 1 = 2, 2 2 = 4, 2 3 = 8, 2 6 = 64 and 2 11 = 2048. [12] The first 3 powers of 2 with all but last digit odd is 2 4 = 16, 2 5 = 32 and 2 9 = 512. The next such power of 2 of form 2 n should have n of at least 6 digits.

  4. Proof of Fermat's Last Theorem for specific exponents

    en.wikipedia.org/wiki/Proof_of_Fermat's_Last...

    Since u 2 + 3v 2 is odd, so is s. A crucial lemma shows that if s is odd and if it satisfies an equation s 3 = u 2 + 3v 2, then it can be written in terms of two integers e and f. s = e 2 + 3f 2. so that u = e(e 2 − 9f 2) v = 3f(e 2 − f 2) u and v are coprime, so e and f must be coprime, too. Since u is even and v odd, e is even and f is ...

  5. Multinomial distribution - Wikipedia

    en.wikipedia.org/wiki/Multinomial_distribution

    When k is 2 and n is bigger than 1, it is the binomial distribution. When k is bigger than 2 and n is 1, it is the categorical distribution . The term "multinoulli" is sometimes used for the categorical distribution to emphasize this four-way relationship (so n determines the suffix, and k the prefix).

  6. Surreal number - Wikipedia

    en.wikipedia.org/wiki/Surreal_number

    The product of this form of ⁠ 1 / 3 ⁠ with any form of 3 is a form whose left set contains only numbers less than 1 and whose right set contains only numbers greater than 1; the birthday property implies that this product is a form of 1.

  7. Graham's number - Wikipedia

    en.wikipedia.org/wiki/Graham's_number

    In other words, G is calculated in 64 steps: the first step is to calculate g 1 with four up-arrows between 3s; the second step is to calculate g 2 with g 1 up-arrows between 3s; the third step is to calculate g 3 with g 2 up-arrows between 3s; and so on, until finally calculating G = g 64 with g 63 up-arrows between 3s.

  8. Permutation - Wikipedia

    en.wikipedia.org/wiki/Permutation

    Thus the lexicographic successor of the initial state is permuted: [1, 2, 4, 3]. Following this algorithm, the next lexicographic permutation will be [1, 3, 2, 4], and the 24th permutation will be [4, 3, 2, 1] at which point a[k] < a[k + 1] does not exist, indicating that this is the last permutation.

  9. Progressive overload - Wikipedia

    en.wikipedia.org/wiki/Progressive_overload

    Progressive overload is a method of strength training and hypertrophy training that advocates for the gradual increase of the stress placed upon the musculoskeletal and nervous system. [1] The principle of progressive overload suggests that the continual increase in the total workload during training sessions will stimulate muscle growth and ...
