COMMENTS

7560 is a highly composite number: A002182(20)=7560.

The sequence is finite with A002183(20)=64 terms: a(64)=7560.

Its primorial factorization is 6^2 * 210 and its representing polynomial p(x) of degree 6 with x=2 is x^6 + 18x^5 + 118x^4 + 348x^3 + 457x^2 + 210x. - Carlos Eduardo Olivieri, May 02 2015
