Recamán's sequence (A005132) is a mathematical sequence, defined as such:
$$A(n) = \begin{cases}0 & \textrm{if } n = 0 \\
A(n-1) - n & \textrm{if } A(n-1) - n \textrm{ is positive and not already in the sequence} \\
% Seems more readable than
%A(n-1) - n & \textrm{if } A(n-1) > n \wedge \not\exi...

Consider the problem: "given a chessboard with one square missing, cut it into 21 L-triominoes". There is a well-known constructive proof that this can be done for any square chessboard s...

String attractors
Let \$S\$ be a string of length \$n\$.
An attractor of \$S\$ is a subset of indices \$A \subset \{0, \ldots, n-1\}\$ such that every nonempty contiguous substring \$S[i \ldots j]\$ of \$S\$ has an occurrence \$S[i' \ld...

In the burial place of King Silo of Asturias there is an inscription that reads SILO PRINCEPS FECIT (King Silo made this).
The first letter is found in the very middle, and from there one reads by going in any non-diagonal direction radiating outward. The final letter is found on all four cor...
Brute-force the switchboard
The other day, our team went to an escape room. One of the puzzles involved a board of six mechanical switches where you had to find the correct combination of on and off in order to unlock a box, somewhat like this:
-v-v-v-
-v-v-v-
Being developers, we decided it ...
The following is a list of dialects of English. Dialects are linguistic varieties which may differ in pronunciation, vocabulary, spelling and grammar. For the classification of varieties of English in terms of pronunciation only, see Regional accents of English.
Dialects can be defined as "sub-forms of languages which are, in general, mutually comprehensible." English speakers from different countries and regions use a variety of different accents (systems of pronunciation), as well as various localized words and grammatical constructions; many different dialects can be identified based on these...
Stød (Danish pronunciation: [støð], also occasionally spelled stod) is a suprasegmental unit of Danish phonology (represented in IPA as ⟨◌ˀ⟩ or as ⟨◌̰⟩), which in its most common form is a kind of creaky voice (laryngealization), but it may also be realized as a glottal stop, especially in emphatic pronunciation. Some dialects of Southern Danish realize stød in a way that is more similar to the tonal word accents of Norwegian and Swedish. In much of Zealand it is regularly realized as something reminiscent of a glottal stop. A probably-unrelated glottal stop, with quite different distribution rules...
