Mathematics
  • It is the tenth prime number, and also the fourth primorial prime.
  • It forms a twin prime pair with thirty-one, which is also a primorial prime. Twenty-nine is also the sixth Sophie Germain prime.[1]
  • It is also the sum of three consecutive squares, 22 + 32 + 42.
  • It is a Lucas prime,[2] a Pell prime,[3] and a tetranacci number.[4]
  • It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. 29 is also the 10th supersingular prime.[5]
  • None of the first 29 natural numbers have more than two different prime factors. This is the longest such consecutive sequence.
  • 29 is a Markov number, appearing in the solutions to x2 + y2 + z2 = 3xyz: {2, 5, 29}, {2, 29, 169}, {5, 29, 433}, {29, 169, 14701}, etc.
  • 29 is a Perrin number, preceded in the sequence by 12, 17, 22.[6]
  • 29 is the smallest positive whole number that cannot be made from the numbers {1, 2, 3, 4}, using each exactly once and using only addition, subtraction, multiplication, and division.[7]
  • It is the number of pentacubes if reflections are considered distinct.

Religion
  • The Bishnois community follows 29 principles. Guru Jambheshwar had laid down 29 principles to be followed by the sect in 1485 A.D. In Hindi, Bish means 20 and noi means 9; thus, Bishnoi translates as Twenty-niners.
