91 (ninety-one) is the natural number following 90 and preceding 92.
Ninety-one is the twenty-seventh distinct biprime and the second of the form (7.q). The aliquot sum of 91 is 21 within the aliquot sequence (91,21,11,1,0) 91 being the fourth composite number in the 11-aliquot tree.
Ninety-one is a triangular number and a hexagonal number, one of the few such numbers to also be a centered hexagonal number, and it is also a centered nonagonal number and a centered cube number. It is the sum of the squares of the first six integers.
It is the smallest positive integer expressible as a sum of two cubes in two different ways if negative roots are allowed: 91 = 63+(-5)3 = 43+33. (See 1729 for more details).
It is also the smallest pseudoprime satisfying the congruence 3n = 3 mod n.[1]
