An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5+1/2, and √2 are not.Every integer greater than 11 is a sum of two composite numbers. The largest prime number with a single-morpheme name. The concatenation of the first 11 factorial numbers is the first such number that is pandigital. The smallest pandigital prime in base 3. The largest prime of form 1!+2!+ … +n!+2, (n=3). Conjecture on primes with one coach relating to the odd integers: iff an integer is in A216371 (primes with one coach either of the form 4q-1 or 4q+1, (q > 0)); the top row of its coach is composed of a permutation of the first q odd integers. Example: prime 19 (q = 5), has 5 terms in each row of its coach: 19: [1, 9, 5, 7, 3] ...
