Unfortunately that doesn't work.  :)

9.to_s(26).tr('0-9a-p', 'a-z') => "j"
(9+10).to_s(26).tr('0-9a-p', 'a-z') => "t"

99.to_s(26).tr('0-9a-p', 'a-z') => "dv"
(99+10).to_s(26).tr('0-9a-p', 'a-z') => "ef"

999.to_s(26).tr('0-9a-p', 'a-z') => "bml"
(999+10).to_s(26).tr('0-9a-p', 'a-z') => "bmv"

9999.to_s(26).tr('0-9a-p', 'a-z') => "oup"
(9999+10).to_s(26).tr('0-9a-p', 'a-z') => "ouz"
