a=1
aa=3
aaa=5
aaaa=7
aaaaa=9
and the even numbers according to their values stand for “b”:
b=2
bb=4
bbb=6
bbbb=8
bbbbb=0
and then? Eureka! We have a Biliteral Cipher in which each letter is represented by one, two, or three, numbers; and so the five symbols of the Baconian Biliteral is reduced to three at maximum.
Variants of this scheme can of course, with a little ingenuity, be easily reconstructed.

Place in their relative order as appearing in the original arrangement the selected symbols of the Biliteral:
