Block Array Constructions

8 Twin Blocks Extend Block Array Jason Summers has found a way to take a previously known method of constructing 4 sets of Twin Blocks from Pi Heptominos, and attach another pair of Twin Blocks at each end, for a construction of a 2 x 8 array of Blocks.

He's also found a way to extend any 2 x n array of Blocks.

In both cases, the preliminary construction for some of the target objects needed are not shown.
