 OFFSET 1,1 COMMENTS If the "Erase or triple" protocol is applied to 1 (see A300148), the biggest integer reached is a(1) = 17010; the next such "altitude" > 17010 is a(2) = 65610 (reached by the integer 10); then the next "altitude" > a(2) is a(3) = 121743 (reached by the integer 23), etc. There are 628 such "altitudes" (the last and biggest one being 29625912486, reached by the integer 3291768054, a pandigital). The sequence is finite. LINKS Table of n, a(n) for n=1..32. CROSSREFS Cf. A300148, A300149, A300150.
