A few quick numbers:
3 is a number of creation/destruction
4 is a number of Satan
6 is a number of hard work/labour (and double 3)
(8 is a number of eternity)
9 is a number of permanence, in terms of endings (which I think includes changes; ending something and causing something else to manifest/be)
11 is a number of Satan
(I think I'm going to get this one wrong again - 13 is a number of eternity)
40 is a powerful, significant number because the Soul works over 40 days (for 40-day workings)
80 is double 40 (for double-40-day workings)
90 is similar to 9 (for 90-day workings; you'd might as well do 10 more days if you did 80 already)
108 is a powerful Satanic number; 1+0+8=9
216 is double 108; 2+1+6=9
666 is the number of the perfected Soul; the Swastika (related to the Black Sun?);
Kabalistic/Magickal Square of the Sun for empowering chakras, strengthening a debilitated Sun, and for help in health and overall spiritual advancement related to the Sun; the Solar/666 Chakra is also for not being lazy, basically
The Runes also work with these numbers and also their own number. The first Rune can be vibrated a multiple of 1; the second, a multiple of 2; the third a multiple of 3; etc. As such, when using numbers, you can use its multiple in a working. 40 days = a full working, but you can do a simple one-off working either to gauge things or to try and get a feel for them. Sister johnson_akemi did a one-off money working, which I think she said took her only a couple of hours. She got some money from that. It's important that once you set on a number (e.g. using 3 for destruction/creation, but using double 3; 6) you never reduce the number (e.g. down to 3 after using double-3); you should either:
- always stay at the same number (double-3), or
- increase (9, 12, etc.), if you can handle it and have the time
that includes starting at 3, increasing to 6, then going back down to 3 is also something to not do. Consider any number you are working with to be the new absolute baseline/'basenumber', the new benchmark - whichever word you prefer to use.
