OEIS Sequences

a(n) = n*(n+1)*(n² - 3·n + 6)/4. A62026

Even Quasi-Carmichael numbers. A262252

a(n) is the number of ways to split [n] = {1,2,...,n} into two (possibly empty) complementary intervals {1,2,...,i} and {i+1,i+2,...,n} and then, if both intervals are nonempty, select 2 nonempty blocks/cells (i.e., subintervals) from each of them, or if one of the intervals is empty, select 2 nonempty blocks/cells from the nonempty interval.
