In Petit sec ("dry Petit"), a player who has the Petit but no other trump nor the Fool must announce this; the hand is voided and this round will be redealt by the next dealer. [14] Common house rules also allow a player to declare a maldonne if their hand has no trumps, or fewer than a given number of combined trumps and face cards.
For example, the base-8 numeral 23 8 contains two digits, "2" and "3", and with a base number (subscripted) "8". When converted to base-10, the 23 8 is equivalent to 19 10 , i.e. 23 8 = 19 10 . In our notation here, the subscript " 8 " of the numeral 23 8 is part of the numeral, but this may not always be the case.
This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters.
q-3, q-4, q-9, q-12 are quadratic nonresidues q-3, q-4, q-9, and, for q > 11, q-12 are primitive roots; If p is a Sophie Germain prime greater than 3, then p must be congruent to 2 mod 3. For, if not, it would be congruent to 1 mod 3 and 2p + 1 would be congruent to 3 mod 3, impossible for a prime number. [16]
In a vigesimal place system, twenty individual numerals (or digit symbols) are used, ten more than in the decimal system. One modern method of finding the extra needed symbols is to write ten as the letter A, or A 20, where the 20 means base 20, to write nineteen as J 20, and the numbers between with the corresponding letters of the alphabet.
