%N Numbers that can be produced from their own digits by applying one or more of the eight operations {+, -, *, /, sqrt(), ^, !, concat11()}, with no operation used more than once, where "concat11()" means the operation of concatenating two single digits.
%C Extending the sequence will soon become impractical without a program to check every possible way to apply one or more of the eight operations. - Editors, Dec 03 2016

%e 0 is a term because sqrt(0) = 0;
%e 24 is a term because (2+sqrt(4))! = 24;
%e 25 is a term because 5^2 = 25;
%e 343 is a term because (3+4)^3 = 343.
