RTT
- Douglas Blumeyer's RTT How-To
- saturation, torsion, contorsion, and defactoring (general audience page, to supplement the existing but more mathematically advanced page)
- defactoring algorithms
- the pathology of enfactoring
- defactoring terminology proposal
- normal lists (revised in collaboration with FloraC to accommodate and enumerate multiple normal forms, and introduced defactored Hermite form)
- matrix echelon forms
- generator size manipulation
- RTT library in Wolfram Language
- intro to exterior algebra for RTT (I did not develop most of this theory, just documented it)
- temperament merging (general audience page, to supplement the existing but more mathematically advanced page Meet and join)
- temperament merging across interval bases (a pragmatic separate look at some of the more advanced ideas found in the above page)
- interval basis (a pragmatic and more basic overview of ideas found on various other pages)
- Talk:Interior product (suggestions re: interior product, progressive product, and regressive product)
- Talk:Meet and Join (suggestions to improve meet & join page)
- Talk:Patent val (proposals to rename "patent val" to "simple map" and "generalized patent val" to "uniform map")
- tuning ranges of regular temperaments (not the original tuning range definitions, but major revisions to terminology and documentation)
- eigenmonzo (I did not coin the term, just created the page, including its essentially built-in proposal to rename itself to "unchanged interval")
- mapping to lattice (again, not my idea, I just gave it an explanation)
- val list (again, not my idea, I just gave it an explanation)
- tuning map (again, not my idea, I just gave it an explanation)
- comma basis (again, not my idea, I just gave it an explanation)
- val#Vals vs. maps (again, not my idea, I just gave it an explanation)
- map (again, not my idea, I just gave it an explanation)
- secor (again, not my idea, I just gave it an edited diagram and history)
- grade (again, not my idea, I just gave it an explanation)
- variance (again, not my idea, I just gave it an explanation)
- dimensions, dimensionality, and rank-nullity theorem (again, not my idea, I just gave it an explanation)
- full-rank and rank-deficiency (again, not my idea, I just gave it an explanation)
- linear dependence (again, not my idea, I just gave it an explanation)
- basis (again, not my idea, I just gave it an explanation)
- temperament addition (I wouldn't claim this is exactly new, conceptually, but it did involve some original thinking)
- uniform map, integer uniform map
- simple map
