Other possible details include startup funds (e.g. US$1M over 10 years), lab space (dry/wet lab, exclusive use square footage), and access to shared facilities (big experimental equipment). Lab space and shared facilities aren't free, so the cost is often deducted from your startup funds.
The first few abundant numbers are 12, 18, 20, 24, 30, 36, 40, 42, 48, ... Note that most of these appear to be even; the first odd one does not appear until 945. This is quite remarkable, as it provides a naturally occurring example of a large number. After 945, the odd-abundant numbers are 1,575, 2,205, 2,835, 3,465, ...
In that class, one student was left out, so 3 is an odd number. An odd number represents a group of paired items with one left out. In other words, odd numbers aren't evenly divisible by 2. When we added one more student to the class, we got an even number of students. But add yet another one, and we're back to one student left out: So, just like even numbers, we can generate odd numbers by adding 2 to an already odd number. We just did that by adding 2 to the odd number 3.
