Let p be prime. Write TgA,hB(p) for the number of two-cycles with the indicated restrictions on g and h, and ChA,aB(p) for the corresponding count in the auxiliary formulation; the symbols ANY, PR, RP, RPPR, ORDh, and ∙ have the meanings fixed earlier in the paper. Let ϕ be Euler's totient function.
Two-cycle counting conjectures.
TgANY,hRP(p)=ChRP,aANY(p)≈2ϕ(p−1),
ThRP,gORDh(p)=ChRP,aRP(p)≈ϕ(p−1)+p−1ϕ(p−1)2,
TgPR,hRP(p)=ChRP,aPR(p)≈p−12ϕ(p−1)2,
TgPR,hRPPR(p)=TgANY,hRPPR(p)=ChRPPR,a∙(p)=Ch∙,aRPPR(p)≈p−1ϕ(p−1)2+(p−1)2ϕ(p−1)3,
ThANY,gORDh(p)=ChANY,aRP(p)≈2ϕ(p−1),
TgPR,hPR(p)=TgANY,hPR(p)=ChPR,aRP(p)≈p−12ϕ(p−1)2.
The equalities in the first, fifth, third, and sixth relations are noted in the source to be exact by symmetry. The asymptotic predictions arise from a random-map heuristic and are not proved in the supplied text.
