According to www.rcaselectron.com RCA made 9, 256, 1024 and 4096 bit
versions of the Selectron tube.
I don't know if any of them other than the 256 bit made it into production.

There was also a 1K by 4 version of this tube.
I've never seen any info on a 1K*4 Selectron, but they weren't even
able to make the 4K*1 work, and the only production tubes were 256*1.
