Michael De Vlieger: Antti, absolutely clearer. Checking A324382 out. (Lots of interruptions today!)

Antti Karttunen: Interesting stuff Michael. One suggestion: "Maximum value in row n = A001221(A002182(n))." would be clearer as: "Maximum value in row n is (given by) A001221(A002182(n))." ??? BTW, have you seen this: https://oeis.org/A324382 I recently submitted. Somewhat related? (although about representing A002182(n) as sums, not products of primorials).
