 OFFSET 1,1 COMMENTS This sequence does not contain any repdigits, unlike A245385. LINKS EXAMPLE 4*84847 = 48484*7 = 339388. Thus 484847 is a member of this sequence. PROG (Python) for n in range(1, 10**7): ..s = str(n) ..count = 0 ..for i in range(1, len(s)): ....if i != len(s) - i: ......if int(s[:i]) != int(s[len(s)-i:]): ........num = int(s[:i])*int(s[i:]) ........if num != 0: ..........if num == int(s[:len(s)-i])*int(s[len(s)-i:]): ............count += 1 ............break ..if count > 0: ....print(n, end=', ') CROSSREFS Cf.
