48 complete B-block peals

I have found 14 sets of round B-blocks which together with some B-blocks exactly cover the extent in an odd number [29 to 35] of round blocks where the sixes can be rearranged to give 48 complete B-blocks. Here is the set of blocks which gives peals.

35 round blocks, signature 54:5+96

These blocks are from a 3-part group.

By bobbing Q-sets the number of bobs can be increased up to 690 bobs.
https://complib.org/composition/97568 645 bobs
https://complib.org/composition/88618 690 bobs - one of 32 examples

The 2017 exact 3-part peals have between 603 and 639 bobs and all have at least one 9 bob run per part; these have between 636 and 690 bobs.

Also
