A challenging build requiring very steady hands to prevent a collapse while building. The bottom part of the bottom units must be placed perfectly straight on a flat ground. The surface is a variety on Schwarz' P surface.
Little error: at 5:04 I say 'another 4', where I should have said 'another 8'...
Counting the magnets of the big build:
a unit has 4 enneagons of 9+18+27 (54) magnets each.
On the center of each enneagon a 6 magnet triangle is placed, so that totals 4*(54+6)= 240 magnets.
On 6 sides 4+8 magnets are placed, 4 central to turn a 'V'-connection into a '^'-connection. On top an extra 8 magnet layer is placed. This totals 240+ 6*(4+8) = 240+ 72 = 312 magnets.
There are 3 shortest '^'-Connections to join 'V'-connections without those 12 magnets: just 4 magnets added. That counts for '^':-12 compared to unconnected unit and 'V':-8 compared to unconnected unit, in total -20.
There are 9 of the second shortest (4+8), with a count of -12.
Complete list:
3 times -20 (-60)
9 * -12 (-108)
18 * -4 (-72)
27 * 4 (+108)
30 * 12 (360)
27 * 20 (540)
18 * 28 (504)
9 * 36 (324)
3 * 44 (132)
This totals to 1728 magnets, in addition to 64 units of 312 each (19968).
This leaves a total count of 21696 magnets.
