Provide means for clustering sequences depending on their similarity

There's a user request in our public page on vk.com: https://vk.com/uniprougene?w=wall-74359225_290, see comments. The problem is the following - there are 250 nucleotide sequences each of 387 bp, and it's required to split them into groups depending on their similarity. The number of groups is less or equal than 10.

Seems like a specific WD worker would be suitable for this.
