* I have no idea what "unit" means that "integer" doesn't cover, and that's covered by mulna'u (see Abstract Algebra). --rlpowell

• • A unit in an integral domain is a number that every number is divisible by; e.g. the units in Z are 1 and -1, and the units in the Gaussian integers are 1, i, -1, and -i. -phma

Oh, OK. This should all have gone in discuss, sorry. My bad.

Here's the discussion that was on the page before I cleaned it up:

• prime: cmuna'ux1 is a prime number in integral domain x2
  • I'd consider that to mean "unit" and not "prime". I suggest:
  • prime: ralju namcu: ralna'un1=r1 is a prime number in integral domain r2
  • Something more like zilterfendi, i should think...
  • unit: jicmu namcu: cmuna'un1=j1 is a unit of integral domain j2
    • I have no idea what "unit" means that "integer" doesn't cover, and that's covered by mulna'u (see Abstract Algebra). --rlpowell
      • A unit in an integral domain is a number that every number is divisible by; e.g. the units in Z are 1 and -1, and the units in the Gaussian integers are 1, i, -1, and -i. -phma
  • "prime" is clearly something with selci. Furthermore, it's clearly a mulna'u; I suggest mulna'usle, which I'll now go put in jbovlaste --rlpowell

The original text of the page had:

n1=j1 is a unit of integral domain j2

for cmuna'u, but that's not what arj entered on jbovlaste. Is this likely to be a problem?
