# SOMA Figures D001025

E-Mail.

NOTE
To describe double set Soma, it is sometimes usefull to have two different notations, to separate the pieces. I use:
Set One: 1,2,3,4,5,6,7
Set Two: V,L,T,Z,A,B,P

## The figure solutions.

```

--------======== DOUBLE SET ========--------

2x #7will make a 2x2x2cube
2x #6will make a 2x2x2cube
6333/2227  Make a 4x2x2box
6637/2677

Here's a neat way to solve THE SENTRY(006) and UP & DOWN(007)
it can also be used as a "transistion":
Build up two set of STAIRS using the flat pieces,
one from each set:
/....1
/...11
/..333
/.4432
/44222
Now, build three 2x2x2 cubes by slapping two #5 pieces together,
two #6 pieces together and two #7 pieces together.
Stack the three large cubes in a COLUMN that is 6-high:
/55/55/66/66/77/77
/55/55/66/66/77/77
The COLUMN and the two STAIRS can now assemble into
the SENTRY TOWER and also the UP & DOWN.

And to the BD011 UP/DOWN.

Sometimes when solving doubles, try to split into
two symmetric parts, each using one set.
I used this in solving D009, D013, D015
