-yllion (Knuth-Pelletier) does not have any direct clarification on the Internet but it does show how the system works on some websites. This system functions like a long scale of -illion. Instead of doubling zero, it quadruples it.This makes the number grow significantly faster than usual -yllion system. For example, byllion in this system will be equal to 1032. While in normal -yllion system, the number will be tryllion. The system also adopt the use of -iliard in the same manner as the long scale of -illion. For example, trylliard will be equal to sextyllion in normal -yllion.
