IMPORTED REVISION FROM WIKISPACES

This is an imported revision from Wikispaces. The revision metadata is included below for reference:

The revision comment was:

The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.

Original Wikitext content:

A [[Harmonic Limit|p-limit]] rational number q can by definition be factored into primes of size less than or equal to p, giving q = 2^e2 3^e3 ... p^ep, where the exponents are integers (positive, negative, or zero.) This is often written in [[http://mathworld.wolfram.com/Bra.html|bra vector]]  notation as <e2 e3 ... ep|, in which case it is called a **monzo**, whee the name refers to the enthusiastic advocacy of [[Joe Monzo]].

The [[Tenney Height|Tenney height]] of this monzo is given by

|| <e2 e3 ... ep| || = |e2| + log2(3)|e3| + ... + log2(p) |ep|

which is a [[http://en.wikipedia.org/wiki/Normed_vector_space|vector space norm]]. The monzos with this norm now define a [[http://en.wikipedia.org/wiki/Lattice_%28group%29|lattice]], which is a discrete subgroup spanning a finite dimensional real normed vector space.
