I'm pretty sure that you must have 15 senators according to the 6th Article in Section 1...
Article 6: Senate
Section 1: The Senate shall be formed of at least 15 members. Anyone is welcome to join the Senate if they so wish as long as they have their paperwork in order, have obtained a free voter ID from the Imgflip DMV, and have been elected or appointed by a stream to represent them. No government stream including IMGFLIP_PRESIDENTS, political party stream, or stream that provides a service to PRESIDENTS such as IMGFLIP_BANK or IMGFLIP_DMV may appoint a Senator.
This was released 10 months ago but the 15 member rule I'm pretty sure still counts
