Hi all, 



These 3 sequences are permutations of the integers for which a(n+1) is either a multiple or a divisor of a(n), unless I did a mistake. 
Are there other instances of such sequences in the OEIS? 


Is there a way to query the OEIS in a single call to get the A_numbers of all sequences that are permutations of the natural numbers? 
Or to get the data of those sequences? 


Thanks and regards. 
MM
