摘要
本文构造了直径为4,6的整树的新类,所构造的两类新的整树包括了[1]中构造出的相应的两类整树,这对于构造其它新的整树可提供一定的参考价值。
A new type of integral trees of diameter 4 and diameter 6 is given in this paper by means of a new lemma. The known results on integal trees of diameter 4 and diameter 6 in some references are the special cases of the results in this Paper.
