$96$ (ninety-six) is:


 * $2^5 \times 3$


 * The $6$th octagonal number, after $1, 8, 21, 40, 65$:
 * $96 = 1 + 7 + 13 + 19 + 25 + 31 = 6 \left({3 \times 6 - 2}\right)$


 * The $5$th untouchable number after $2, 5, 52, 88$.


 * The $22$nd semiperfect number after $6, 12, 18, 20, 24, 28, 30, 36, 40, 42, 48, 54, 56, 60, 66, 72, 78, 80, 84, 88, 90$:
 * $96 = 16 + 32 + 48$


 * The $2$nd positive integer after $64$ with $6$ or more prime factors:
 * $64 = 2 \times 2 \times 2 \times 2 \times 2 \times 3$


 * The $4$th even integer after $2, 4, 94$ that cannot be expressed as the sum of $2$ prime numbers which are each one of a pair of twin primes.


 * The $28$th positive integer which is not the sum of $1$ or more distinct squares:
 * $2, 3, 6, 7, 8, 11, 12, 15, 18, 19, 22, 23, 24, 27, 28, 31, 32, 33, 43, 44, 47, 48, 60, 67, 72, 76, 92, 96, \ldots$


 * The $48$th positive integer after $2, 3, 4, 7, 8, \ldots, 61, 65, 66, 67, 72, 77, 80, 81, 84, 89, 94, 95$ which cannot be expressed as the sum of distinct pentagonal numbers.
