(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A129124 (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. 0
238, 257, 277, 337, 525, 699, 911, 1135, 1147, 1257, 1349, 1466, 1504, 1544, 1664, 1992, 2024 (list; graph; refs; listen; history; text; internal format)

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
