%N Smallest primes from A029710, each belonging to those different residue class of mod 210 which are listed in A078860. Arranged according to possible least positive residues mod 210.

%e Several terms are equal to corresponding ones in A078860, while others are larger like: 397=210.1+187 where r=187 is in A078860.

%t f[x_] := Mod[Prime[x], 210] d[x_] := Prime[x+1]-Prime[x] t=Table[0, {210}]; Do[s=f[n]; If[Equal[d[n], 4]&&s<211&&t[[s]]==0, t[[s]]=Prime[n]], {n, 1, 10000}]; t
