Role

Adult ordinary model; exposed solution separate from genuine blank own work

Complete source

Day 52 ordinary costume tag source, 364+278=642.

Full alternative

An adult model of 364+278 tags. Partitioning gives 500+130+12. Twelve ones rename as one ten and two ones, so 500+140+2. Fourteen tens rename as one hundred and four tens, yielding 600+40+2=642. The tag quantity remains the same through each renaming. A separate chunk check also yields 642.
