Default Small numbers with the longest 2*3 drivers

It is believed that any driver, in particular 2*3 driver, breaks sooner or later. But for how long such a driver can continue unbroken? I searched small numbers with the driver 2*3 for as long driver run as possible.

Here are the results. The smallest number with unbroken driver 2*3 for the moment is 708534. It is currently at 142 digits. Record keepers among smaller numbers are:
Code:
2010   breaks at 16 digits,  drive length 109
3306   breaks at 22 digits,  drive length 157
8154   breaks at 40 digits,  drive length 320
29070  breaks at 42 digits,  drive length 331
29190  breaks at 46 digits,  drive length 354
45570  breaks at 49 digits,  drive length 440
56562  breaks at 59 digits,  drive length 449
113454 breaks at 96 digits,  drive length 842
199290 breaks at 101 digits, drive length 821
295662 breaks at 130 digits, drive length 1371
384726 breaks at 141 digits, drive length 1348
