it's probably not true but b is between 2 and H.

Jolly Jocker,

From your info I have this:

[16jY7qLJnxHBp3dqwV2kzYq1LucfZzgxsH    ,eeb9ab334df2770d]

my bet based on your data is that #64 is between edf9cd60356dcc19:eeb9ab334df2770d
but that is probably not true.

Edit: b is after H in the Base58 Alphabet do with that what you will
