[seqfan] A031996 and co

[michel.marcus at free.fr]

Dear all, 


For me, A031996 and A031998, A031999, A032341, A032342 are all duplicates of earlier sequences. 
Except that they lack first term 0. 
For instance A031996 is the same as A023753 Plaindromes: numbers whose digits in base 12 are in nondecreasing order. 


Do you agree that they should be dead ? 


Best. 
Michel
