Two infinite classes of perfect codes in metrically regular graphs

A new such infinite class of perfect 1 codes, and also a new infinite class of antipodal graphs, will be defined in this paper. ...
If rr maps Ii onto the threespace ljlk , then 7~ maps IiT onto the threespace Ijslk7. From this remark it follows easily that 7~ maps 4 onto the threespace I$, , where {i,j, k} = (1,2, 3). ...

Because rates of SSR mutation are positively correlated with SSR length (ELLEGREN 2004), we divided SSRs into two classes based on size (class 1, 220 bp; class II, 12 to =19 bp). ...
Using this strategy we integrated 320 new SSR markers and 29 non-SSR markers into the existing genetic map. ...
