regular octagon loops

in the UK this task was devised by SEAC (a national assessment agency), many moons ago
green plastic octagon templates were distributed to all UK schools
they might be lurking, dustily, in cupboards

you can buy regular octagon paper plates for a group to work with
but accurate recording is still difficult...

















the 'growing in a line' case could be explored using a semi-regular tessellation of regular octagons and squares
