the sum of the sums of the divisors of the first 10 positive integers.
the thirtieth semiprime, and the twenty-sixth distinct semiprime and the eighth of the form (3.q).
together with 85 and 86, forms the last semiprime in the 2nd cluster of three consecutive semiprimes; the first comprising 33, 34, 35.
with an aliquot sum of 33; itself a semiprime, within an aliquot sequence of five composite numbers (87,33,15,9,4,3,1,0) to the Prime in the 3-aliquot tree.
5! - 4! - 3! - 2! - 1! = 87
