Looking at the lights that go off in a powercut on our street it seems
to be R-R-Y-Y-B-B-R-R-Y-Y-B-B etc The incoming supply runs down the
garden between a pair of semis, feeds one cut out and then feeds back
across the garden to the next semis cutout.

Is the looping normally visible - ie at the riser - or underground?

Usually from the main fuse.
