EXAMPLE

19 is present as A272565(19)=5 and 5 < A020639(19)=19. (19 is right after 5 on the third row of array A255127 while on A083221 it occurs at the beginning of row 8 that starts with 19 itself).
49 is present as it occurs as the fourth number on the third row of A255127 beginning with 5: 5, 19, 35, 49, ..., thus A272565(49)=5, while in A083221 49 occurs right after 7 on row 4, thus A020639(49)=7, and 5 < 7.
