First I tried to solve the Honneamise number system by checking the countdown timer in the movie, but later I found a picture from a movie art exhibition, where the numbers and letters were defined. It was revealed that Honneamise number system is base-13, so number 32 is expressed as 26. The letters are like Japanese hiragana consisting of a consonant and a vowel. Literally these symbols should read "Geto26".
