Haiku Stairs Haiku Stairs The Haikū Stairs, also known as the Stairway to Heaven or Haikū Ladder, is a steep hiking trail on the island of Oahu, Hawaii. The total 3,922 steps span along Oahu's Ko'olau mountain range. "Haiku" does not refer to the Japanese poetry genre. The area is named "Haikū" after the Kahili flower. In 1942, contractors for the U.S. Navy began construction of the Haʻikū Radio Station, a top secret facility that was to be used to transmit radio signals to Navy ships that were then operating throughout the Pacific. In order to obtain the necessary height for the
Invariant of a binary form for the ring of covariants. showed that the ring of invariants of a degree 8 form is generated by 9 invariants of degrees 2, 3, 4, 5, 6, 7, 8, 9, 10, and the ring of covariants is generated by 69 covariants. August von Gall () and confirmed the generators for the ring of invariants and showed that the ideal of relations between them is generated by elements of degrees 16, 17, 18, 19, 20. showed that the algebra of invariants of a degree 9 form is generated by 92 invariants. Cröni, Hagedorn, and Brouwer computed 476 covariants, and Lercier
