We report on large-scale, regular morphological patterns found in the radiojet of the nearby radio galaxy NGC 6251. Investigating morphological propertiesof this radio jet from the nucleus to a radial distance of $\sim$ 300 arcsec($\approx$ 140 kpc) mapped at 1662 MHz and 4885 MHz by Perley, Bridle, &Willis, we find three chains, each of which consists of five radio knots. Wealso find that eight radio knots in the first two chains consist of three smallsub-knots (the triple-knotty substructures). We discuss the observationalproperties of these regular morphological patterns.Comment: 8 figures, 15 pages, accepted for publication in A
