Left-Truncated Automorphic Number is Automorphic/Examples/1,787,109,376

Example of Left-Truncated Automorphic Number is Automorphic
We have that $1 \, 787 \, 109 \, 376$ is automorphic:
 * $1 \, 787 \, 109 \, 376^2 = 3 \, 193 \, 759 \, 92 \, \mathbf {1 \, 787 \, 109 \, 376}$

Hence so is $109 \, 376$:
 * $109 \, 376^2 = 11 \, 963 \, \mathbf {109 \, 376}$
