at 155 I'm looking for a number.

Counting all the numbers gives me 173 which is an irrelevant number for me. He had also thought of a magic square although it would not have much to do with it.

And if I only think about what the image tells me about "counting numbers" that can be interpreted in several ways: one count alone or add multiply to see if there is some kind of "pattern" that follows a logic.

If I paint, for example, of each different color a number of those that are repeated the most below, it seems that I obtain a type of encryption.

At the moment those are my ideas
