(c,n) is the n-th number for which the Esucarys sequence starting from it reaches 247 and from there keeps indefinitely this value.

	OFFSET	`1,1`
	LINKS	`Table of n, a(n) for n=1..6.`
	EXAMPLE	`For c < 1247 none sequence starting from c except 247 itself reaches 247` `S(1247)=2473 then E(1247) = 3742` `S(3742)=7420 then E(3742) = 247 then (c,1) = 247 and (c,2) = 1247`
