Philip knows his numbers

[wrog]

1	13	14	6*	6
2	5	15	11	8
3	7	10	16	61**
4	17	18	12	20

Philip has now reproduced the above arrangement of numbered blocks something like 5 times in the past week or two.

I keep resetting it to the correct arrangement

1	2	4	8	16
13	7	14	9	18
17	15	11	3	6
12	5	10	20†	19††

to no avail.

<td>††</td><td>yeah I know 19 isn't quite right here, but it's the only remaining block, so bite me.</td>

*	upside-down 9
**	upside-down 19
†	hey, it works
