The Number That Builds Itself
145.xyz
145.xyz is one of the most mathematically fascinating numbers in existence.
145 is a factorion, a number that equals the sum of the factorials of its digits: 1! + 4! + 5! = 1 + 24 + 120 = 145. Only four factorions exist in all of mathematics: 1, 2, 145, and 40585.
Beyond mathematics, 145 carries deep cultural and technical significance.
145.800 MHz is the frequency astronauts use to talk to Earth from the International Space Station.
In music, I-IV-V (1-4-5) is the chord progression that forms the backbone of Blues, Rock, Folk, and Country. Three chords. Infinite songs. And 145 BPM is the heartbeat of psytrance, the exact tempo that drives the genre.
This domain is ideal for any technology or educational venture rooted in mathematics, music, or communication.
As a three-digit numerical .xyz domain, 145.xyz is part of an extremely scarce category. Only 1,000 such domains exist. While some three-digit .xyz domains in this registry carry premiums as high as $55,000 per year, this domain renews at the standard rate.
According to ICANN rules, a domain registered at the standard rate stays at the standard rate as long as it remains active. You have guaranteed low costs forever.
The .xyz extension reinforces the technical and creative nature of the brand while keeping it accessible and memorable.
One of only four factorions in existence.
