Reporting negative results for the tandem g7 receiver search:

Bait:

Block and pi precursors.

Catalysts added:

block, tub, barge, transp. block/hive/ship/loaf/tub/pond, eater, ship+eater, block+eater,

hook with tail, dual eater, bookend on pedestal, BTS, eater2.

Timing constraints:

2 catalysts ~ gen 50 (one of them could be transparent)

1 catalyst ~ gen 70 (opaque)

1 catalyst ~ gen 80 (opaque)

1 catalyst ~ gen 90 (opaque)

==================

5 catalysts, at most one of them transperant.
