%N Triangle read by rows with T(n,k) = n - A195313(k), n>=1, k>=1, if (n - A195313(k))>=0.
%C Also triangle read by rows in which column k lists the nonnegative integers A001477 starting at the row A195313(k).
%C This sequence is related to the generalized tridecagonal numbers A195313, A195843 and A196933 in the same way as A195310 is related to the generalized pentagonal numbers A001318, A175003 and A000041. See comments in A195825.
