Ask HN: Is a string of identical blue star-shaped stickers considered a pattern?

We're having a contest at work where participants are allowed to select any color of star-shaped sticker to place beside their name when they accomplish a certain task.

One of the participants mentioned that they were "going for the same pattern" so they selected the same blue star that they've used for every single entry in their row.

Is a string of identical blue stars, or a string of the same character like "aaaaaaaaaaaaaaa" considered a pattern? Or is that something else?
