A062387 Squares in which removing a suitably chosen digit yields another square and this process can be continued until the digits are exhausted. 2

%N Squares in which removing a suitably chosen digit yields another square and this process can be continued until the digits are exhausted.

%C The sequence is infinite because 100 times any term produces another term. - _Harvey P. Dale_, May 05 2018

%e 1296 = 36^2 belongs to the sequence as removing 2 yields 196 = 14^2. Removing a 9 from 196 yields 16, removing 6 yields 1 and all are perfect squares.

%Y Cf. A034377, A034378.

%O 1,2
