a(n) = floor( φ*a(n-1) ) + floor( φ*a(n-2) ), where φ is the golden ratio. A5908

Heinz number of the multiset of run-sums of the prime indices of n. A353832

Number of distinct runs in the n-th composition in standard order. A351014

Composition run-sum transformation in terms of standard composition numbers. The a(k)-th composition in standard order is the sequence of run-sums of the k-th composition in standard order. Takes each index of a row of A066099 to the index of the row consisting of its run-sums. A353847

Numbers whose multiset of prime indices has all equal run-sums. A353833
