Summary, etc. <p>Systematic study of superheavy nuclei <sup>296</sup>Og and its possibilities to emit alpha particle and heavier clusters are studied using Modified Generalized Liquid Drop Model (MGLDM) with Q value dependent preformation factor. Half-lives and branching ratio of all possible cluster emission of <sup>296</sup>Og is checked and only those cluster which are within the experimental half-lives limit (less than 10<sup>30</sup>s) and branching ratio limit (down to 10<sup>-19</sup>) are considered. Among this, <sup>88</sup>Kr is found to be the most probable heavy cluster, leading to doubly magic <sup>208</sup>Pb daughter nuclei, with half-lives comparable with alpha decay half-lives. Thus the role of doubly magic daughter nuclei in cluster decay is highlighted here. Again the decay modes of <sup>296</sup>Og are also studied by comparing alpha decay half-lives using MGLDM with spontaneous fission half-lives proposed by Bao <em>et al.</em>, and from this, it is found that for superheavy element <sup>296</sup>Og, decays by 3 alpha chains followed by spontaneous fission. We hope that this study would help when this emission is experimentally detected in near future.</p>
