Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

(c,n) is the n-th number for which the Esucarys sequence starting from it reaches 238 and from there runs in a 18 steps loop.

EXAMPLE
For c<257 except 238 itself, sequences E(c) never reaches 238
S(257) = 772 then E(257) =277
S(277) = 832 then E(277)= 238 then (c,1) = 238 and (c,2)=257
