Examples of template usage and data table generating
The category for Carol/Kynea primes holds 3 example pages for some bases (2, 6 and 10).
These pages hold their data in the template CarolKyneaBase using named parameters.
The parameters can be used to create automatically a table of those pages.Examples for including PDF documents
- Show document starting at page 3 and different sizings:
Example for fetching data from RieselPrime database
The data are collected from the internal SQL database by Extension:External Data:
- table: RieselPrime
- field: rieselk_id = 4 (-> "1" = Mersenne primes)
- fields collected: n, comment, utm (prime index n, comment like "Woodall", utm: id of Top5000 page)
Functioning but still complicated: no parser/string functions allowed in "#for_external_table" statement, therefore using variables.
Mersenne primes [math]\displaystyle{ 2^n-1 }[/math], prime for n:
- 2*, 3, 5*, 7*, 13, 17, 19*, 31, 61, 89, 107, 127, 521, 607, 1279, 2203, 2281, 3217, 4253, 4423, 9689, 9941, 11213, 19937, 21701, 23209, 44497, 86243, 110503, 132049, 216091, 756839, 859433, 1257787, 1398269, 2976221, 3021377, 6972593, 13466917, 20996011, 24036583, 25964951, 30402457, 32582657, 37156667, 42643801, 43112609, 57885161,
Examples for showing images of external pages
Images from external sources have to be put as full link on a page.
