The Digits ABCABD

How many possible 6 digit numbers are there of the form N=abcabd N=\overline{abcabd} where a0,d0 a \neq 0, d \neq 0, d=c+1d = c + 1 and N N is a perfect square?

Details and assumptions

The condition of a0a \neq 0 follows because we have a 6 digit number.
The condition of d0 d \neq 0 follows because 09+1 0 \neq 9 + 1 .
