This is numbers name? 343 free fixed points, 147 one fixed
points, 21 two fixed points, 1 three fixed points
Or
343 free (0)matching numbers, 147 one (1) matching numbers,
21 two (2) matching numbers, 1 three (3) matching numbers
fixed points?
matching numbers?
Example:
A059056 Penrice Christmas gift numbers, Card-matching
numbers (Dinner-Diner matching numbers).
