COMMENTS

Also triangle read by rows in which column k lists the nonnegative integers A001477 starting at the row A085787(k).

This sequence is related to the generalized heptagonal numbers A085787, A195837 and A036820 in the same way as A195310 is related to the generalized pentagonal numbers A001318, A175003 and A000041. See comments in A195825.
