What is the most space-efficient way to encode this binary sequence of 4 bytes?

[11111111] [11111111] [11111111] [11111111]

Select one option from the list

treat all 4 bytes as 32-bit number [11111111111111111111111111111111] and encode it with 5 symbols

split them in 5-bit groups [11111] [11111] [11111] [11111] [11111] [11111] [11000] [00000] and encode

split them in 4-bit groups [1111] [1111] [1111] [1111] [1111] [1111] [1111] [1111] and encode

split them in 6-bit groups [111111] [111111] [111111] [111111] [111111] [110000] [ ] [ ] and encode
