Question: In which year NGC 166 is located by an american astronomer who also discovered Frank Muller and Ormond Stone

Passages:
NGC 166 (also known as PGC 2143) is a spiral galaxy located around 2.6 million light-years away in the constellation Cetus, with an apparent magnitude of 15.18.  It was discovered by Francis Preserved Leavenworth in 1886. Frank Muller (September 10, 1862 – April 19, 1917) was an American astronomer. NGC 7016 is an elliptical or lenticular galaxy located about 480 million Light-years away from Earth in the constellation Capricornus.  NGC 7016's calculated velocity is 11,046 km/s.  NGC 7016 has an estimated diameter of about 140 thousand light years.  NGC 7016 was discovered by American astronomer Francis Preserved Leavenworth on July 8, 1885. NGC 1614 is the "New General Catalogue" identifier for a spiral galaxy in the equatorial constellation of Eridanus.  It was discovered on December 29, 1885 by American astronomer Lewis Swift, who described it in a shorthand notation as: pretty faint, small, round, a little brighter middle.  The nebula was then catalogued by Danish-Irish astronomer J. L. E. Drayer in 1888.  When direct photography became available, it was noted that this galaxy displayed some conspicuous peculiarities.  American astronomer Halton Arp included it in his 1966 "Atlas of Peculiar Galaxies".  In 1971, Swiss astronomer Fritz Zwicky described it as a "blue post-eruptive galaxy, compact patchy core, spiral plumes, long blue jet SSW". Francis Preserved Leavenworth (born September 3, 1858 in Mount Vernon, Indiana; died November 12, 1928; a.k.a. "Frank Leavenworth") was an American astronomer.  He discovered many New General Catalogue objects together with Frank Muller and Ormond Stone.  They used a telescope with a 66-cm aperture at the Leander McCormick Observatory at the University of Virginia in Charlottesville, Virginia. Ormond Stone (January 11, 1847 – January 17, 1933), was an American astronomer, mathematician and educator.  He was the director of Cincinnati Observatory and subsequently the first director of the McCormick Observatory at the University of Virginia, where he trained a significant number of scientists.  He served as the editor of the "Annals of Mathematics" and towards the end of his life made donations which led to the founding of the Fairfax Public Library System. NGC 6285 is an interacting spiral galaxy located in the constellation Draco.  It is designated as S0-a in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift in 1886.  NGC 6285 is located at about 262 million light years away from earth.  NGC 6285 and NGC 6286 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies<ref name="NASA/IPAC"> </ref> NGC 178 is a spiral galaxy in the constellation of Cetus.  The compiler of the New General Catalogue, John Louis Emil Dreyer noted that NGC 178 was "faint, small, much extended 0°, brighter middle".  It was discovered on November 3, 1885 by Ormond Stone. NGC 6286 is an interacting spiral galaxy located in the constellation Draco.  It is designated as Sb/P in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift on 13 August 1885.  NGC 6286 is located at about 252 million light years away from Earth.  NGC 6286 and NGC 6285 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies. <ref name="NASA/IPAC"> </ref> NGC 7035 and NGC 7035A are a pair of interacting lenticular galaxies located around 400 to 430 million light-years away in the constellation of Capricornus.  The main galaxy, NGC 7035 was discovered by astronomer Frank Muller in 1886.
