COMMENT

If continued,odd palindrom with 0 as center. Note complementarity between -1 (in A144477) and 0. There exist a 0-th spectrum from atomic hydrogen for numerators, b(n) and for denominators, c(n). From A144437, b(0)=1 ;from A005408, b(1)=1 ;from A144433, b(2)=1 ; ;from A005563(4),A061037(4),A061039(4),A061041(4),A061043(4),A061045(4),A061047(4),A061049(4)=24,2,40,3,56,4,72,5, b(4)=1 . From A147560,via A046162, c(0)=0 ;from A035287, c(1)=0 ;from A061038(2),A061042(2),A061046(2),A061050(2)=16,144,576,1600=A060300(n+1), c(2)=0 ; ;from A061038(4),A061042(4),A061046(4),A061050(4)=9,64,225,576=A099761(n+1), c(4)=0 .
