Generate a Recovery Phrase With Three D8 Dice and Two Coins

Each set of three D8 rolls and two coin flips produces exactly one 11-bit word index. Repeat the five results for 12 or 24 provisional words, then follow the final-word procedure.

Use the dice results in order as First D8, Second D8, and Third D8. Record heads as H (value 0) and tails as T (value 1).

Result Value
Heads 0
Tails 1

The word index is calculated as:

(First D8 - 1) * 256 + (Second D8 - 1) * 32 + (Third D8 - 1) * 4 + First coin * 2 + Second coin

This mapping produces every index from 0 to 2047 exactly once, with every combination of the three dice and two coins represented.
