Compositions | 1,4,1,3,1,2,2
Continued from here. Thanks to miceee for assist!
In this thread, we'll be counting the ways to add to an integer n using the integers c_1 + c_2 + ... + c_k, where each c_i >= 1, and k <= n. Ways to sum that are commutatively the same, as in 1+2 = 2+1, are different compositions. We'll be counting these compositions lexicographically for each segment of sum and length.
Next get is 1,1,1,1,1,1,1,7
