  The Seyfert galaxy NGC 2639 was known to exhibit three episodes of AGN
jet/lobe activity. We present here the upgraded Giant Metrewave Radio Telescope
(uGMRT) 735 MHz image of NGC 2639 showing a fourth episode as witnessed by the
discovery of $\sim9$ kpc radio lobes misaligned with the previously known
$\sim1.5$ kpc, $\sim360$ parsec, and $\sim3$ parsec jet features detected
through the Karl G. Jansky Very Large Array (VLA) and the Very Long Baseline
Array (VLBA), respectively. Using the spectral ageing software BRATS, we derive
the ages of the $\sim9$ kpc, $\sim1.5$ kpc, and $\sim360$ parsec episodes to
be, respectively, $34^{+4}_{-6}$ Myr, $11.8^{+1.7}_{-1.4}$ Myr, and
$2.8^{+0.7}_{-0.5}$ Myr, and conclude that minor mergers occurred $9-22$ Myr
apart. NGC 2639 shows a deficit of molecular gas in its central $\sim6$ kpc
region. The GALEX NUV image also shows a deficiency of recent star-formation in
the same region, while the star formation rate (SFR) surface density in NGC
2639 is lower by a factor of $5-18$ compared to the global Schmidt law of
star-forming galaxies. This makes NGC 2639 a rare case of a Seyfert galaxy
showing episodic jet activity and possible signatures of jet-driven AGN
feedback.
