perplexus.info :: Numbers : A stretch of 8… or more…

A stretch of 8… or more… (Posted on 2023-04-30)

1, 4, 9, 36, 81, 100, 121, … , 225, … represent squares such that the sum of digits of each of them is also a square number.

From 81 to 225 there are seven consecutive squares.

Where about is another run of consecutive 7?
Maybe 8 or more?
What is the present “state of art”?
How far could you explore ?
