Re: Another Double Beryl composition for the Plain Bob Ringer

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?
