 Jan 5 awarded Popular Question Jun 7 accepted Triangular numbers divided by $3$? Jun 6 comment Triangular numbers divided by $3$? @PrasunBiswas $N$ is the total number of coins, which is the triangular number. If you are talking about the $number of rows = 6$ then $N=21$ & $m=7$. Jun 6 revised Triangular numbers divided by $3$? added 232 characters in body Jun 6 comment Triangular numbers divided by $3$? @PrasunBiswas $m=5$ for $N=15$ & $m=7$ for $N=21$. I'm not sure if it'll be clear how from my notes, but here are the snaps from my notebook: inft.ly/3Psf2ZC, inft.ly/3gq2yVq Jun 6 comment Triangular numbers divided by $3$? I'm not talking about the same moves, but the same type of moves which was based on my algorithm. But that is of no interest here, the same moves will never work. But the result was consistent with $N/3$ for as far as I checked Jun 6 comment Triangular numbers divided by $3$? @alkabary I did as far as I could. I initially tried to approach this problem with a moderately complex algorithm based on a divide & conquer strategy. The answer always came as $N/3$, and I cannot figure out why it is so.

It's not a complain, an acquaintance whom I told that I don't think 2K13 is correct brought this up to me, so was just confirming.
