Re: Another Double Beryl composition for the Plain Bob Ringer

[Sam Ratliff <sratliff118 gmail com>]

Started playing around with 6th place bobs (credit to David Wilson for the 
suggestion to try out different calls) and, to my surprise, calling a 6th 
place bob at the first lead end yields 13527486 at the next lead end. 
Thus, bp x7 with 6th place bobs yields a 224 of Double Beryl that contains 
all plain bob lead ends. Who’da’thunk’it?
