The number of conjugacy classes of pairs of commuting elements in a finite group G is the cardinal cardinality of the set {c(a,b) | a,b in G and ab=ba} where c(a,b) = {(gag^(-1),gbg^(-1)) | g in G}.

The number of conjugacy classes of pairs of commuting elements in a finite group G equals is the number cardinal of conjugacy classes within the centralizers of class representatives of G. This reformulation, demonstrated set {c(a,b) | a,b in the linked MathOverflow post, was employed G and ab=ba} where c(a,b) = {(gag^(-1),gbg^(-1)) | g in the sequence-generating programG}.
It is equal to the number of conjugacy classes within the centralizers of class representatives of G.
This reformulation was employed in the sequence-generating program.
It is also equal to the rank of the modular fusion category Z(Rep(G)), the Drinfeld center of Rep(G).
These reformulation are demonstrated in the linked MathOverflow post.
