Also, if the table has cell spacing (and thus border-collapse=separate), meaning that cells have separate borders with a gap in between, that gap will still be visible. A cruder way to align columns of numbers is to use a figure space   or   , which is intended to be the width of a numeral, though is font-dependent in practice:
Using the border-collapse property to combine the double borders, ... {Help: Table/example row template | 50 ... In the first line of table code, ...
In mathematical logic and set theory, an ordinal collapsing function (or projection function) is a technique for defining (notations for) certain recursive large countable ordinals, whose principle is to give names to certain ordinals much larger than the one being defined, perhaps even large cardinals (though they can be replaced with recursively large ordinals at the cost of extra technical ...
Adding the mw-collapsible class to a table automatically positions the toggle, and selects which parts to collapse. A common use is to make a collapsible layout table, which always displays an introduction or summary, but hides the rest of the content from immediate view.
In mathematics, Rathjen's psi function is an ordinal collapsing function developed by Michael Rathjen. It collapses weakly Mahlo cardinals M {\displaystyle M} to generate large countable ordinals . [ 1 ]
The Feferman–Schütte ordinal can be defined as the smallest ordinal that cannot be obtained by starting with 0 and using the operations of ordinal addition and the Veblen functions φ α (β). That is, it is the smallest α such that φ α (0) = α .
Folds can be regarded as consistently replacing the structural components of a data structure with functions and values. Lists, for example, are built up in many functional languages from two primitives: any list is either an empty list, commonly called nil ([]), or is constructed by prefixing an element in front of another list, creating what is called a cons node ( Cons(X1,Cons(X2,Cons ...
Buchholz defined his functions as follows. Define: Ω ξ = ω ξ if ξ > 0, Ω 0 = 1; The functions ψ v (α) for α an ordinal, v an ordinal at most ω, are defined by induction on α as follows: ψ v (α) is the smallest ordinal not in C v (α) where C v (α) is the smallest set such that C v (α) contains all ordinals less than Ω v
